Aviation officials grounded a Costa Rican charter flight company after one of its planes crashed New Year's Eve, killing the Steinberg family from Scarsdale.

Nature Air's operating certificate was recently suspended by Costa Rica's civil aviation authority as investigators sought a cause for the crash that killed all 12 on the plane, including Irene and Bruce Steinberg, and their sons Matthew, Zachary and William, according to media reports in Costa Rica.

The disciplinary action comes as the Westchester County community mourned the unthinkable tragedy. Rabbi Jonathan Blake of Westchester Reform Temple recently posted on social media his euology for the Steinbergs and others killed in the crash.

"Twelve vibrant lives, two cherished families, one guide and two crew, all snuffed out in a blinding instant, and the hopes and dreams that die with them — we are mourning them all," Blake said, "all the unfulfilled potential, all the graduations and first loves and weddings, all the potential for another generation of children and grandchildren, all the healing work that yet could have been brought to bear on a hurting world, all the laughter and love and hope — all gone."

Aviation officials in Costa Rica didn't return a request for comment on the suspension of Nature Air's certificate. The company also didn't respond to an email and phone call.

Media outlets in Costa Rica reported that officials pulled Nature Air's operating license because the company didn't have enough staff to keep flying its planes, citing the death of the pilot and co-pilot on Dec. 31.

Ladd Sanger, a prominent aviation attorney, described the suspension as incredibly rare.

"What we have is Nature Air has had a couple of crashes and this accident has pulled back the curtain probably on some operational issues at the company," he said.

Sanger asserted aviation regulators likely found repeated or intentional violations in order to justify suspending an entire airline operation. He noted pulling a certificate affects many other flights and business at Nature Air.

"This is an extraordinary step, and I'm only aware of one other situation where this (suspension penalty) was even at issue," he said, "This accident has caused regulators to find some things to give them great concern."

Costa Rican investigators said they are trying to determine the cause of the crash, but that it was most likely the result of strong winds or mechanical problems. It happened about 140 miles from the capital of San Jose.

The Steinbergs died in a flight that took off shortly after another plane in their private charter group landed safely.

The first flight took off with 10 passengers at about 11 a.m., landing safely about 40 minutes later in San Jose. The second aircraft, carrying the Steinbergs and a family of four from Florida, took off around noon and crashed within minutes, killing everyone on board, said Nelson Vega, general manager of Nature Air.
